VII. Inner Processes in the Human Organism. Sense-Perception, Breathing, Sleeping, Waking, Memory

What has actually happened? If we were to sleep according to the laws of the physical world—I do not now mean the body, for the body sleeps according to those laws as a matter of course—but if in the conditions of existence outside the physical and etheric bodies, in our ego and our astral body, our sleep were governed by the same laws which govern our waking life by day, this movement backwards would not be possible, for we should simply have to go forward with the flow of time. We are subject to altogether different laws when in our astral body and ego we are outside the physical and etheric bodies.
